Try to be as specific as possible, does it die while in motion or standing still, do all dash lights go out, does it crank but not start or refire tight away, dies when you turn on high beam or ..., any work done recently (ie added lights, horn, fuzzy dice
) accident, does it feel like fueling or lack of , anything at all that you can think of.
Some of the obvious things to check would be side stand switch and wiring, kill switch and wiring, ignition switch and wiring.
Good luck ghost issues really suck.
